Ah Ok that makes more sense
If the rated RPM of the motor is stated as above then you should manage 1000rpm approx so at 2.5mm approx per rev that would work out at 2500mm/min so sounds like your tuning may be needing looked at.

Sorry Dennis, never used Gecko servos so dont know how to tune them. What kernel are you using and what pulse width do you have set in Motor Tuning?

I have the geckos adjusted so don't need to do anything here for kernel speed it's set to 3500 and the step pulse is 2.

There must be a reason your drives are faulting, do the Geckos tell you what the fault is or does the drive just fault with no way of knowing why?
What are your steps per unit set to?

No indicator on the geckos they just fault out don't know why. as to the steps they are calibrated for each axis but they distance is perfect no problem as i have them moving in exact amounts just the faulting issue is my only problem.

Could be overcurrent, maybe reducing your accel a bit will allow faster rapids. What do you have the accel set to?

Might be worth reducing it a bit to see if you can increase the Velocity.

So if i lower the accel then can increase the velocity is that how it works ? so what is your thought on how low it should be and then how high would i go on the velocity ?
